Proteins expressed during anaerobic growth. Media contained LBK buffered with 100 mM HOMOPIPES, pH 4.5 (A); 100 mM MES–50 mM propionic acid, pH 6.2 (B); 100 mM MOPS, pH 7.0 (C); or 100 mM AMPSO, pH 9.0 (D). The horizontal axes represent pH values; the vertical axes represent molecular weights in thousands.
